As Stormy Daniels gets ready to “tell her story” about a night in July 2006 when she allegedly had sex with Donald Trump, she may have a way to back it up, The Blast reported.

The porn star has a “Monica Lewinsky dress,” the site said, citing sources close to Daniels. Daniels’ dress is a gold mini dress she wore during the alleged tryst in a Lake Tahoe hotel with the man who would become president.

She’s kept the dress “in pristine condition” and plans to have it forensically tested for samples of hair, skin or “anything else” that would contain DNA, reported The Blast, which also shared a photo of the dress in its report.

On Wednesday, a manager for Daniels, whose real name is Stephanie Clifford, told the Associated Press that a non-disclosure agreement the actress signed to keep the president’s secrets is no longer valid.

That’s because Trump’s personal attorney Michael Cohen violated the agreement himself by disclosing on Tuesday that he personally paid Daniels $130,000 in “a private transaction,” just before Election Day, Gina Rodriguez, a manager for Daniels, told the Associated Press. Cohen’s disclosure to The New York Times was followed by a story in the Daily Beast that reported that the lawyer was shopping a book proposal that would address Daniels’ story.

The fact that Cohen is commenting on the six-figure payout means Daniels is free to tell her side, Rodriguez said to the Associated Press.

The Blast also reported earlier that Daniels’ representatives have contacted Trump’s legal team to inform them that she believes she’s free to spill details of the alleged encounter, which she says took place at a celebrity golf tournament in Lake Tahoe in July 2006.

“Everything is off now, and Stormy is going to tell her story,” Rodriguez told The Blast.

Following the alleged encounter, which took place four months after Trump’s third wife, Melania Trump, gave birth to their son, Barron, Daniels told friends about it. She also detailed her alleged extramarital relationship with Trump in a 2011 interview that was published on the celebrity website The Dirty. Moreover, she shared her story with In Touch in 2011, but that outlet didn’t publish her story at the time.

A month before the presidential election, the website The Smoking Gun published an account of the relationship, but it went mostly unnoticed by mainstream outlets. Daniels also began sharing details about the alleged year-long affair with Slate’s executive editor Jacob Weisberg, but backed off going on the record just before the election.

The agreement between Daniels and Cohen allegedly called for each party to say nothing about the incident, or to even acknowledge the existence of a nondisclosure agreement.

Daniels apparently honored her side of the agreement. She also allowed Cohen to release a letter signed by her in which she denied an affair took place after the Wall Street Journal first reported on the payout in mid-January.

She also played it coy during a Jan. 30 appearance on “Jimmy Kimmel Live,” Slate reported. And before Kimmel’s show, she released another statement, again denying the affair and thereby again contradicting comments she was reported to have given to multiple journalists and others over the years, the Washington Post reported.

By disclosing this week that he paid Daniels $130,000 out of his own pocket, Cohen was trying to minimize the involvement of Trump or of his campaign in the arrangement.

But Cohen’s efforts may have instead complicated matters, with Daniels now claiming that she’s free to speak up.
